SNC2D Unit D: Research Questions (Part 2)

 Recycling


Why we do it: The largest source of human-caused methane emissions, which is a greenhouse gas 21 times more powerful than carbon dioxide. According to the Environmental Protection Agency (EPA) all landfill liners, a low permeable barrier under-engineered landfill sites, will leak their toxic leachate which can then contaminate soil and underground water supplies. Recycling diverts this waste from the landfills preventing these problems. Of course, that isn’t the only positive. Recycling also conserves energy, saves energy, feeds a green economy, and overall contributes to a healthy environment. 


How we do it: The recycling process can be divided into three basic steps. First is the collection and processing. Curbside collection, dropoff centers, and deposit or refund programs are some of many methods for collecting recyclables after which, the recyclables are sorted, cleaned, and processed into materials at a recovery facility. The second step of this process is manufacturing. The processed materials from the recovery facility are manufactured into more and more of today's products. The final step of the process is purchasing new products made from recycled materials. As there are thousands of products that contain recycled content nowadays anyone can help the recycling loop by buying new products made from recycled materials.
